  • Estimation of Cronbach’s alpha for sparse datasets

    Lopez, M. (2007)

    Conference item
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    Cronbach’s alpha is widely used to evaluate the internal consistency of a psychometric instrument. Its popularity is largely based on a straightforward interpretation in terms of correlations, its ease of calculation and the guidance it gives to building a single dimensional scale. The standard calculation of alpha, however, requires a complete dataset and can give misleading results with sparse datasets. An alternative method of calculating an equivalent to Cronbach’s alpha is proposed that retains the essence of alpha and can be readily calculated for sparse datasets. A theoretical basis is given and the method is evaluated and validated against generated datasets.

    Comins, N.; Young, A. (2007)

    Conference item
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    This paper describes the use of a commercial Enterprise Resource Planning (ERP) system in an undergraduate degree course. It will describe the process of deciding on which system to use, the implementation of several different ERP systems and the integration of the system into the curriculum of the course. The paper will also discuss the different pedagogical uses of the system, the different ways in which such a system can be implemented and the advantages and disadvantages of the different systems that were implemented. The paper will conclude with lecturer and student feedback on the process and application of employing such a large system into the course to enhance the teaching and learning of a business information system to computing students..

  • Key attributes for success within the ICT job market: a case study of ICT students' view

    Asgarkhani, M.; Wan, J. (2007)

    Conference item
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    This paper elaborates on attributes that are seen as being critical to success within the ICT sector roles. The required attributes as identified by a study of 205 randomly selected ICT roles have been compared with students’ perception (based on the preliminary results of a study of one student focus group). Overall, there were difficulties in drawing clear conclusions from the outcome of one case study only. However, we were able to identify some key issues in both agreements and mismatches on winning attributes for future studies.

  • Where's the bling of the thing? Ethics, gaming and PBL-1

    McCarthy, D. (2007)

    Conference item
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    This paper describes an evaluation of PBL-Interactive (PBL-I), an authoring tool for an ethical decision making game, within the Dip ICT course, ET600 Ethics and professionalism, at Christchurch Polytechnic, Institute of Technology, (CPIT). The tool was developed through the e-Learning Collaborative Development Fund (eCDF) for use in online and face to face delivery. While the prototype was developed and the usability testing conducted with student volunteers returned positive results, the limitations of the authoring tool in a multilinear gaming environment outweighed its affordances. In particular, the authoring mode interface lacked ease of use and functionality for advanced features such as video and audio required to develop multiple ethical choices to motivate students with advanced gaming experience in online and face to face learning environments.

  • The ICT journey from diplomas to degrees: the CPIT staircasing experience

    Nesbit, T.; McCarthy, C. (2007)

    Conference item
    Christchurch Polytechnic Institute of Technology, Te Wānanga Ōtautahi

    The purpose of this paper is to explore aspects of the pathways from diploma level study in Information and Communication Technology (ICT) to degree level study in ICT. The aspects explored include the role that such pathways play for students who for a variety of reasons did not enter degree level study upon leaving the school education system and to evaluate their success rates when they transferred to degree level study mid way through their degree. Over seventy (70 students) who have completed the Diploma in Information and Communications Technology Level 6 (DipICT L6) have transferred into the Bachelor of Information and Communication Technologies (BICT) at Christchurch Polytechnic Institute of Technology since 2002. These students are exempted from completing 180 credits of the 360 credits that are required for the BICT degree. This paper compares the success rates of these students in the BICT courses that they complete with the success rates of students who entered the BICT degree at year one and draws the conclusions that these students have success rates that are on a par with those of other students in the BICT degree and that the Staircasing arrangement that is in place is successful.

  • International IPO underpricing, earnings quality, and governance

    Boulton, Thomas J; Smart, Scott B; Zutter, Chad J (2007-03-20)

    Conference item
    University of Otago

    Examining a sample of more than 4,600 IPOs across 24 countries from 2000-2004, we find that firm- and deal-specific characteristics widely used in IPO single-country underpricing studies (e.g., offer size, underwriter reputation, and industry) can explain variation in an international cross section of initial returns. More importantly, we also find that country-level measures of earnings quality and governance characteristics explain differences in the international cross section of IPO underpricing. We find lower initial returns in countries with higher earnings quality and that underpricing is generally higher in countries with corporate governance systems that strengthen the position of investors relative to insiders.

  • What’s in a vote? The short- and long-run impact of dual-class equity on IPO firm values

    Smart, Scott B; Thirumalai, Rhamabhadran; Zutter, Chad J (2007-03-09)

    Conference item
    University of Otago

    We find that relative to fundamentals, dual-class firms trade at lower prices than do singleclass firms both at the IPO date and for at least the subsequent five years. The lower prices attached to dual-class firms do not foreshadow abnormally low stock or accounting returns. However, CEO turnover events do occur less frequently among dual-class firms and the circumstances surrounding CEO turnover vary between single- and dual-class companies. When dual-class firms unify their share classes statistically and economically significant value gains occur. Collectively, our results suggest that the governance associated with dual-class equity influences the pricing of dual-class firms.

  • Of the people, for the people, by the people: He tangata, He tangata, He tangata - The value of autobiography in academia: Maori women and Post World War Two American Presidents

    Warbrick, Paerau (2007-12-10)

    Conference item
    University of Otago

    The catch phrase title of this presentation Of the people, for the people, by the people: He tangata, He tangata, He tangata will be immediately recognised by scholars of American history and Maori studies. The expression Of the people, for the people, by the people is taken from US President Abraham Lincoln’s Gettysberg address at the height of the American Civil War in 1863. Although it is in reference to democracy in the American republic, its literal form in my opinion alludes to the very essence of autobiographies. They are written by people about themselves and they are given to wider audience. And so there is a democratic essence about autobiographies. Any fool, dimwit or halfwit can create an autobiography. And you know what, that is the beautiful nature of them. They can be as formalistic or artistic as the author wants it to be. I now turn to the Maori expression in the catch phrase title. This is an expression taken from a Maori proverb that ponders He aha te mea nui o te ao, he tangata he tangata he tangata The meaning roughly translates as What is the most important thing in the world, it is the people, the people, the people. And again, this expression’s significance is that autobiographies are a product of people. People and indeed the person is clearly at the centre of the narrative or to use a Maori term, the centre of the korero. In this presentation I explore the value of autobiographies in academia.

  • An explanation of unbiased expectations and efficient market hypothesis using Markov switching framework

    Bhattacharya, Prasad S; Singh, Harminder (2007-03-23)

    Conference item
    University of Otago

    This paper uses Indian stock futures data to explore unbiased expectations and efficient market hypothesis. Having experienced voluminous transactions within a short time span after its establishment, the Indian stock futures market provides an unparalleled case for exploring these issues involving expectation and efficiency. Besides analyzing market efficiency between cash and futures prices using cointegration and error correction frameworks, the efficiency hypothesis is also investigated after explicitly modeling the underlying state of the market (expansion or contraction) through the first-order Markov switching set-up. The results based on Markov switching analysis show that relatively longer time horizon is more effective in eliminating arbitrage opportunities than the short run.

  • Agency Problems and Audit Fees: Further Tests of the Free Cash Flow Hypothesis

    Griffin, Paul A; Lont, David H; Sun, Yuan (2007)

    Conference item
    University of Otago

    This study finds that the agency problems of companies with high free cash flow (FCF) and low growth opportunities induce auditors of companies in the United States to raise audit fees to compensate for the additional effort. We also find that high FCF companies with high growth prospects have higher audit fees. In both cases, higher debt levels moderate the increased fees, consistent with the role of debt as a monitoring mechanism. Other mechanisms to mitigate the agency costs of FCF such as dividend payout and share repurchase (not studied earlier) do not moderate the higher audit fees.
